FIELD OF DISCLOSURE

The disclosure relates to the field of plant breeding and, morespecifically, to the tomato variety NUN 09271 TOF. The disclosurefurther relates to vegetative reproductions of tomato variety NUN 09271TOF, methods for tissue culture of tomato variety NUN 09271 TOF, methodsfor regenerating a plant from such a tissue culture, and to phenotypicvariants of tomato variety NUN 09271 TOF. The disclosure also relates toprogeny of tomato variety NUN 09271 TOF and the hybrid varietiesobtained by crossing tomato variety NUN 09271 TOF as a parent line withplants of other varieties or parent lines.

BACKGROUND

The goal of plant breeding is to combine various desirable traits in asingle variety. Such desirable traits may include greater yield,resistance to diseases, insects or other pests, tolerance to heat anddrought, better agronomic quality, higher nutritional value, enhancedgrowth rate and improved fruit properties.

Breeding techniques take advantage of a plant's method of pollination.There are two general methods of pollination: self-pollination andcross-pollination. A plant self-pollinates if pollen from one flower istransferred to the same or another flower of the same genotype. A plantcross-pollinates if pollen comes to it from a flower of a differentgenotype.

Plants that have been self-pollinated and selected for (uniform) typeover many generations become homozygous at almost all gene loci andproduce a uniform population of true breeding progeny of homozygousplants. A cross between two such homozygous plants of different linesproduces a uniform population of hybrid plants that are heterozygous formany gene loci. The extent of heterozygosity in the hybrid is a functionof the genetic distance between the parents. Conversely, a cross of twoplants each heterozygous at a number of loci produces a segregatingpopulation of hybrid plants that differ genetically and are not uniform.The resulting non-uniformity makes performance unpredictable.

The development of uniform varieties requires the development ofhomozygous inbred plants, the crossing of these inbred plants to makehybrids, and the evaluation of the hybrids resulting from the crosses.Pedigree breeding and recurrent selection are examples of breedingmethods that have been used to develop inbred plants from breedingpopulations. Those breeding methods combine the genetic backgrounds fromtwo or more plants or various other broad-based sources into breedingpools from which new lines are developed by selfing and selection ofdesired phenotypes. The new plants are evaluated to determine which havecommercial potential.

Tomato (Solanum lycopersicum and closely related species) is naturally adiploid and the basic chromosome number of the genus is x=12, most are2n=2x=24, including the cultivated ones. It originated in the New Worldand has since become a major food crop.

Tomato cultivars may be grouped by maturity, i.e., the time requiredfrom planting the seed to the stage where fruit harvest can occur.Standard maturity classifications include ‘early’, ‘midseason’ or‘late-maturing.’ Another classification for tomatoes is thedevelopmental timing of fruit set. ‘Determinate’ plants grow foliage,then transition into a reproductive phase of flower setting, pollinationand fruit development. Consequently, determinant cultivars have a largeproportion of the fruit ripen within a short time frame. Growers thatharvest only once in a season favor determinant type cultivars. Incontrast, ‘indeterminate’ types grow foliage, then enter a long phasewhere flower and fruit development proceed along with new foliar growth.Growers that harvest the same plants multiple times favor indeterminatetype cultivars.

Tomatoes can also be classified by their target markets: fresh marketand processing tomatoes. Fresh-market tomatoes are primarily used forsalads, salad bar and sandwiches, and require good storage properties.On the other hand, processing tomatoes generally requires red coloredand pink to red/crimson fruit flesh and higher percentage of solublesolids. Processing tomatoes can be canned whole, canned, diced orchopped, dried, roasted, pasted, puréed or concentrated, juiced, frozen,or put into ready-made dishes, for example, sauces, stews or soups.

In 2017, World Atlas (available at world-wide web word atlas underarticles/which-are-the-world-s-leading-tomato-producing-countries)reported that the worldwide production of tomatoes amounted to 170.8million tons. United States is ranked as the third largest producer oftomatoes in the world, next to China and India. Tomatoes are availablein the United States year-round, with California and Florida being themajor producers. Fresh-market tomatoes are available from May toDecember although supply peaks in July and in September through October.Processing tomatoes have the greatest supply from August to September.

In response to more recent consumer demands for dietary diversity,tomato breeders have developed a wider range of colors. In addition toexpanding the range of red colored fruits, there are cultivars thatproduce fruits that are creamy white, lime green, yellow, green, golden,orange and purple. Additionally, there are multi-colored varietiesexemplified by mainly red fruited varieties with green shoulders, andboth striped- and variegated-colored fruit.

“RHS” refers to the Royal Horticultural Society (RHS) which publishes anofficial botanical color chart quantitatively identifying colorsaccording to a defined numbering system. The chart may be purchased fromRoyal Horticulture Society Enterprise Ltd RHS Garden; Wisley, Woking;Surrey GU236QB, UK, e.g., the RHS color chart 2007.

“Reference Variety for NUN 09271 TOF” refers herein to variety SassariRZ F1, a variety from Rijk Zwaan, which has been planted in a trialtogether with NUN 09271 TOF. The characteristics of tomato variety NUN09271 TOF are compared with the characteristics of the Reference Varietyas shown in Tables 2-3. The distinguishing characteristics betweentomato variety NUN 09271 TOF and the Reference Variety are shown inTable 4.

A plant having “all the physiological and morphological characteristics”of a referred-to-plant means a plant showing the physiological andmorphological characteristics of the referred-to-plant when grown underthe same environmental conditions, preferably in the same experiment;the referred-to-plant can be a plant from which it was derived, e.g.,the progenitor plant, the parent, the recurrent parent, the plant usedfor tissue- or cell culture, etc. A physiological or morphologicalcharacteristic can be a numerical characteristic or a non-numericalcharacteristic. In one aspect, a plant has “all but one, two or three ofthe physiological and morphological characteristics” of areferred-to-plant, or “all the physiological and morphologicalcharacteristics” of Tables 1-3 or “all or all but one, two or three ofthe physiological and morphological characteristics” of Tables 1-3.

The physiological and/or morphological characteristics mentioned aboveare commonly evaluated at significance levels of 1%, 5% or 10% if theyare numerical (quantitative), or for having an identical degree (ortype) if not numerical (not quantitative), if measured under the sameenvironmental conditions. For example, a progeny plant or a Single LocusConverted plant or a mutated plant of variety NUN 09271 TOF, may haveone or more (or all) of the essential physiological and/or morphologicalcharacteristics of said variety listed in Tables 1-3, as determined atthe 5% significance level (i.e., p<0.05) for numerical characteristicsand determined by type or degree for non-numerical characteristics, whengrown under the same environmental conditions.

“Distinguishing characteristics” or “distinguishing morphological and/orphysiological characteristics” refers herein to the characteristicswhich distinguish (i.e., are different) between the new variety andother tomato varieties, such as the Reference Variety, when grown underthe same environmental conditions. The distinguishing characteristicsbetween tomato variety NUN 09271 TOF and Reference Variety are describedin Table 4. When comparing tomato variety NUN 09271 TOF with differentvarieties, the distinguishing characteristics may be different. In oneaspect, the distinguishing characteristics may therefore include atleast one, two, three or more (or all) of the characteristics listed inTables 1-3.

Tomato variety NUN 09271 TOF has the following distinguishingcharacteristics when compared to the Reference Variety as shown in Table4: 1) no anthocyanin coloration of upper third stem; 2) shorter steminternode; 3) broader mature leaf; 4) larger size of leaflets (middle ofleaf); 5) lighter intensity of green color of mature leaf; 6) lessglossy mature leaf; 7) weaker mature leaf blistering; 8) horizontalattitude of petiole of leaflet in relation to main axis; 9) longerpeduncle; 10) larger mature fruit; 11) smaller blossom scar; 12) smallercore in cross section; 13) thinner pericarp; 14) two or three locules;15) firmer mature fruit; and 16) later time of flowering, when grownunder the same environmental conditions.

Thus, a tomato plant “comprising the distinguishing characteristics oftomato variety NUN 09271 TOF” (such as a progeny plant) refers herein toa plant which does not differ significantly from said variety in thedistinguishing characteristics above. Therefore, in one aspect, thedisclosure provides a plant that does not differ significantly fromtomato variety NUN 09271 TOF in the distinguishing characteristicsabove.

Similarity and differences between two different plant lines orvarieties can be determined by comparing the number of morphologicaland/or physiological characteristics (e.g., the characteristics aslisted in Tables 1-3) that are the same (i.e., statistically notsignificantly different) or that are different (i.e., statisticallysignificantly different) between the two plant lines or varieties whengrown under the same environmental conditions. A numericalcharacteristic is considered to be “the same” when the value for anumeric characteristic is not significantly different at the 1% (p<0.01)or 5% (p<0.05) significance level, using T-test, a standard method knownto the skilled person. A non-numerical or “degree” or “type”characteristic is considered “the same” when the values have the same“degree” or “type” when scored using USDA and/or UPOV descriptors, ifthe plants are grown under the same environmental conditions.

“Variety” or “cultivar” means a plant grouping within a single botanicaltaxon of the lowest rank.

A “plant line” is, for example, a breeding line which can be used todevelop one or more varieties. A breeding line is typically highlyhomozygous.

“Harvested seeds” refer to seeds harvested from a line or variety, e.g.,produced after self-fertilization or cross-fertilization and collected.

“Hybrid variety” or “F1 hybrid” refers to the seeds harvested fromcrossing two inbred (nearly homozygous) parental lines. For example, thefemale parent is pollinated with pollen of the male parent to producehybrid (F1) seeds on the female parent.

“Locus” (plural loci) refers to the specific location, place or site ofa DNA sequence on a chromosome, where, for example, a gene or geneticmarker is found. A locus may confer a specific trait.

“Allele” refers to one or more alternative forms of a gene locus. All ofthese loci relate to one trait. Sometimes, different alleles can resultin different observable phenotypic traits, such as differentpigmentation. However, many variations at the genetic level result inlittle or no observable variation. If a multicellular organism has twosets of chromosomes, i.e., diploid, these chromosomes are referred to ashomologous chromosomes, i.e., diploid. Diploid organisms have one copyof each gene (and therefore one allele) on each chromosome. If bothalleles are the same, they are homozygotes. If the alleles aredifferent, they are heterozygotes.

“Genotype” refers to the genetic composition of a cell or organism.

“Phenotype” refers to the detectable characteristic of a plant, cell, ororganism, which characteristics are the manifestation of geneexpression.

“Haploid” refers to a cell or organism having one set of the two sets ofchromosomes in a diploid.

“Diploid” refers to a plant, a vegetative plant part(s), or seed which adiploid plant can be grown, having two sets of chromosomes, designatedherein as 2n.

“Triploid” refers to a plant, a vegetative plant part(s), or seed whicha diploid plant can be grown, having three sets of chromosomes,designated herein as 3n.

“Tetraploid” refers to a plant, a vegetative plant part(s), or seedwhich a diploid plant can be grown, having four sets of chromosomes,designated herein as 4n.

“Scion” refers to a part of the plant attached to the rootstock. Thisplant is selected for its stems, leaves, flowers, or fruits. The scioncontains the desired genes to be duplicated in future production by thestock/scion plant and may produce the desired tomato fruit.

“Rootstock” or “stock” refers to the plant selected for its roots, inparticular for the resistance of the roots to diseases or stress (e.g.,heat, cold, salinity etc.). Normally the quality of the fruit of theplant providing the rootstock is less important.

“Stock/scion” or grafted plant refers to a tomato plant comprising arootstock from one plant grafted to a scion from another plant.

“Grafting” refers to the method of joining of (genetically) differentplant parts, especially scions and rootstocks, together so that theygrow as a single plant. A grafted seedling or a grafted plant is aseedling or plant (produced by grafting) consisting of such differentplant parts and which grows as one plant.

The term “traditional breeding techniques” encompasses herein crossing,selfing, selection, doubled haploid production, embryo rescue,protoplast fusion, marker assisted selection, mutation breeding, etc. asknown to the breeder (e.g., methods other than geneticmodification/transformation/transgenic methods), by which, for example,a genetically heritable trait can be transferred from one tomato line orvariety to another.

“Tissue culture” or “cell culture” refers to a composition comprisingisolated cells of the same or a different type or a collection of suchcells organized into parts of a plant. Tissue culture of various tissuesof tomato and regeneration of plants therefrom is well known and widelypublished (see, e.g., Bhatia et al. (2004), Plant Cell, Tissue and OrganCulture 78: 1-21). Similarly, methods of preparing cell cultures areknown in the art.

“Regeneration” refers to the development of a plant from cell culture ortissue culture or vegetative propagation.

“Vegetative propagation,” “vegetative reproduction,” or “clonalpropagation” are used interchangeably herein and mean a method of takinga part of a plant and allowing that plant part to form at least roots,and also refer to the plant or plantlet obtained by that method.Optionally, the vegetative propagation is grown into a mature plant. Theskilled person is aware of what plant parts are suitable for use in themethod.

“Selfing” refers to self-pollination of a plant, i.e., the transfer ofpollen from the anther to the stigma of the same plant.

“Crossing” refers to the mating of two parent plants. The termencompasses “cross-pollination” and “selfing”.

“Cross-pollination” refers to the fertilization by the union of twogametes from different plants.

“Backcrossing” is a traditional breeding technique used to introduce atrait into a plant line or variety. The plant containing the trait iscalled the donor plant and the plant into which the trait is transferredis called the recurrent parent. An initial cross is made between thedonor parent and the recurrent parent to produce a progeny plant.Progeny plants which have the trait are then crossed to the recurrentparent. After several generations of backcrossing and/or selfing therecurrent parent comprises the trait of the donor. The plant generatedin this way may be referred to as a “single trait converted plant”. Thetechnique can also be used on a parental line of a hybrid.

“Progeny” as used herein refers to a plant obtained from a plantdesignated NUN 09271 TOF. A progeny may be obtained by regeneration ofcell culture or tissue culture or parts of a plant of said variety orselfing of a plant of said variety or by producing seeds of a plant ofsaid variety. In further aspects, progeny may also encompass plantsobtained from crossing of at least one plant of said variety withanother tomato plant of the same variety or another variety or(breeding) line, or with wild tomato plants. A progeny may comprise amutation or a transgene. A “first generation progeny” or is the progenydirectly derived from, obtained from, obtainable from or derivable fromthe parent plant by, e.g., traditional breeding methods (selfing and/orcross-pollinating) or regeneration (optimally combined withtransformation or mutation). Thus, a plant of variety NUN 09271 TOF isthe male parent, the female parent or both of a first generation progenyof that variety. Progeny may have all the physiological andmorphological characteristics of variety NUN 09271 TOF, when grown underthe same environmental conditions. Using common breeding methods such asbackcrossing or recurrent selection, mutation or transformation, one ormore specific characteristics may be introduced into said variety, toprovide a plant comprising all but 1, 2, or 3 or more of themorphological and physiological characteristics of variety NUN 09271 TOF(as listed in Tables 1-3).

The terms “gene converted” or “conversion plant” or “single locusconverted plant” in this context refer to tomato plants which aredeveloped by traditional breeding techniques e.g., backcrossing, or viagenetic engineering or through mutation breeding, wherein essentiallyall of the desired morphological and physiological characteristics ofthe parent variety or line are recovered, in addition to the one or moregenes transferred into the parent via e.g., the backcrossing technique(optionally including reverse breeding or reverse synthesis of breedinglines). It is understood that not only the addition of a furthercharacteristic (e.g., addition of gene conferring a furthercharacteristic, such as a disease resistance gene), but also thereplacement/modification of an existing characteristic by a differentcharacteristic is encompassed herein (e.g., mutant allele of a gene canmodify the phenotype of a characteristic).

Likewise, a “Single Locus Converted (Conversion) Plant” refers to plantsdeveloped by plant breeding techniques comprising or consisting ofmutation and/or by genetic transformation and/or by traditional breedingtechniques, such as backcrossing, wherein essentially all of the desiredmorphological and physiological characteristics of a tomato variety arerecovered in addition to the characteristics of the single locus havingbeen transferred into the variety via the above mentioned technique. Incase of a hybrid, the gene may be introduced in the male or femaleparental line.

“Transgene” or “chimeric gene” refers to a genetic locus comprising aDNA sequence which has been introduced into the genome of the plant bytransformation. A plant comprising a transgene stably integrated intoits genome is referred to as “transgenic plant.”

As used herein, the terms “resistance” and “tolerance” are usedinterchangeably to describe plants that show no symptoms orsignificantly reduced symptoms to a specified biotic pest, pathogen,abiotic influence or environmental condition compared to a susceptibleplant. These terms are optionally also used to describe plants showingsome symptoms but that are still able to produce marketable product withan acceptable yield.

“Average” refers herein to the arithmetic mean.

The term “mean” refers to the arithmetic mean of several measurements.The skilled person understands that the appearance of a plant depends tosome extent on the growing conditions of said plant. The mean, if notindicated otherwise within this application, refers to the arithmeticmean of measurements on at least 10 different, randomly selected plantsof a variety or line.

Forbreeding methods in general, see, e.g., Principles of Plant Genetics andBreeding, 2007, George Acquaah, Blackwell Publishing, ISBN-13:978-1-4051-3646-4.

In one aspect, pedigree selection is used as a breeding method fordeveloping a tomato variety. Pedigree selection is also known as the“Vilmorin System of Selection,” see, e.g., Allard, John Wiley & Sons,Inc., 1999, pp. 64-67. In general, selection is first practiced among F2plants. In the next season, the most desirable F3 lines are firstidentified, then desirable F3 plants within each line are selected. Thefollowing season and in all subsequent generations of inbreeding, themost desirable families are identified first, then desirable lineswithin the selected families are chosen. A family refers to lines thatwere derived from plants selected from the same progeny from thepreceding generation.

Thus, progeny in connection with pedigree selection are either thegeneration (seeds) produced from the first cross (F1) or selfing (S1),or any further generation produced by crossing and/or selfing (F2, F3,etc.) and/or backcrossing (BC1, BC2, etc.) one or more selected plantsof the F1 and/or S1 and/or BC1 generation (or plants of any furthergeneration, e.g., F2) with another tomato plant (and/or with a wildrelative of tomato). Progeny may have all the physiological andmorphological characteristics of tomato variety NUN 09271 TOF, whengrown under the same environmental conditions and/or progeny may have(be selected for having) one or more of the distinguishingcharacteristics of tomato variety NUN 09271 TOF.

The relatedness can, for example, be determined byfingerprinting techniques (e.g., making use of isozyme markers and/ormolecular markers such as Single-nucleotide polymorphism (SNP) markers,amplified fragment length polymorphism (AFLP) markers, microsatellites,minisatellites, Random Amplified Polymorphic DNA (RAPD) markers,restriction fragment length polymorphism (RFLP) markers and others). Aplant is “closely related” to tomato variety NUN 09271 TOF if its DNAfingerprint is at least 80%, 90%, 95% or 98% identical to thefingerprint of that variety. In a particular aspect, AFLP markers areused for DNA fingerprinting (see, e.g., Vos et al. 1995, Nucleic AcidResearch 23: 4407-4414). A closely related plant may have a Jaccard'sSimilarity index of at least about 0.8, preferably at least about 0.9,0.95, 0.98 or more (see, e.g., Sharifova, S., et. al., (2013), Journalof Hort.

In other aspects, the tomato plant comprises thedistinguishing characteristics of tomato variety NUN 09271 TOF.

For the purpose of this disclosure, the “sequence identity” ofnucleotide sequences, expressed as a percentage, refers to the number ofpositions in the two optimally aligned sequences which have identicalresidues (×100) divided by the number of positions compared. A gap,i.e., a position in the pairwise alignment where a residue is present inone sequence but not in the other, is regarded as a position withnon-identical residues. A pairwise global sequence alignment of twonucleotide sequences is found by aligning the two sequences over theentire length according to the Needleman and Wunsch global alignmentalgorithm described in Needleman and Wunsch, 1970, J. Mol. Biol.48(3):443-53). A full implementation of the Needleman-Wunsch globalalignment algorithm is found in the needle program in The EuropeanMolecular Biology Open Software Suite (see, e.g., EMBOSS, Rice et al.,Trends in Genetics June 2000, vol. 16, No. 6. pp. 276-277).

In one aspect, a plant of variety NUN 09271 TOF may also be mutated (bye.g., irradiation, chemical mutagenesis, heat treatment, etc.) andmutated seeds or plants may be selected in order to change one or morecharacteristics of said variety. Methods such as TILLING (TargetingInduced Local Lesions in Genomes) may be applied to tomato populationsin order to identify mutants.

Similarly, tomato variety NUN 09271 TOF may be transformed andregenerated, whereby one or more chimeric genes are introduced into thevariety or into a plant comprising all but 1, 2, 3, or more of themorphological and physiological characteristics (e.g., as listed inTables 1-3). Many useful traits can be introduced into tomato varietyNUN 09271 TOF by e.g., crossing a tomato variety NUN 09271 TOF with atransgenic tomato plant comprising a desired transgene, as well as bydirectly introducing a transgene into tomato variety NUN 09271 TOF bygenetic transformation techniques.

Any pest or disease resistance genes may be introduced into a plant oftomato variety NUN 09271 TOF, progeny of said variety or into a plantcomprising all but 1, 2, or 3 or more of the morphological andphysiological characteristics of tomato variety NUN 09271 TOF (e.g., aslisted in Tables 1-3). Resistance to one or more of the followingdiseases or pests may be introduced into the plant described herein:Colorado potato beetle, Southern root knot nematode, Spider mites,Sugarfly beet army worm, Tobacco flea beetle, Tomato hornworm, Tomatofruitworm, Whitefly, Bacterial canker, Bacterial soft rot, Bacterialspeck, Bacterial wilt (Pseudomonas syringae pv. Tomato), Bacterial,Anthracnose (Gloeosporium piperatum), Brown rot or corky root(Pyrenochaeta lycopersici), Alternaria, Fusarium wilt (F. oxysporumraces), Gray leaf spot (Stemphylium spp), Late blight (Phytophthorainfestans races), and Leaf mold (Cladosporium fulvum races), Nematode(Meloidogyne spp.), Verticillium Wilt (Verticillium dahliae), Ralstoniasolanacearum (Rs), Leveillula Taurica (Lt), and/or Oidium neolycopersici(On). Other resistance genes, against pathogenic viruses (e.g., TomatoMosaic Virus (ToMV), Curly TOF Virus, Tomato Mottle Virus, Potato YVirus, Blotchey Ripening, Tobacco Etch Virus, the various Tobacco MosaicVirus races, Concentric cracking, Tomato Spotted Wilt Virus (TSWV),Tomato Yellow Leaf Curl Virus (TYLCV), Gold Fleck, Tomato Torrado Virus(ToTV)), fungi, bacteria, nematodes, insects or other pests may also beintroduced.

Genetic transformation may, therefore, be used to insert a selectedtransgene into the tomato plants of the disclosure described herein ormay, alternatively, be used for the preparation of transgenic tomatoplants which can be used as a source of the transgene(s), which can beintroduced into tomato variety NUN 09271 TOF by e.g., backcrossing. Agenetic trait which has been engineered into the genome of a particulartomato plant may then be moved into the genome of another tomato plant(e.g., another variety) using traditional breeding techniques which arewell-known in the art. For example, backcrossing is commonly used tomove a transgene from a transformed tomato variety into an alreadydeveloped tomato variety and the resulting backcross conversion plantwill then comprise the transgene(s).

Any DNA sequences, whether from a different species or from the samespecies, which are inserted into the genome using transformation, arereferred to herein collectively as “transgenes.” A “transgene” alsoencompasses antisense, or sense and antisense sequences capable of genesilencing. Thus, the disclosure also relates to transgenic plants oftomato variety NUN 09271 TOF. In some aspects, a transgenic plant oftomato variety NUN 09271 TOF may contain at least one transgene butcould also contain at least 1, 2, 3, 4, or more transgenes.

Plant transformation involves the construction of an expression vectorwhich will function in plant cells. Such a vector comprises DNAcomprising a gene under control of, or operatively linked to aregulatory element active in plant cells (e.g., promoter). Theexpression vector may contain one or more such operably linkedgene/regulatory element combinations. The vector may be in the form of aplasmid and can be used alone or in combination with other plasmids toprovide transformed tomato plants using transformation methods toincorporate transgenes into the genetic material of the tomato plant(s).Transformation can be carried out using standard methods, such asAgrobacterium tumefaciens mediated transformation, electroporation,biolistics particle delivery system, or microprojectile bombardment,followed by selection of the transformed cells and regeneration intoplants.

Plants can also be genetically engineered, modified, or manipulated toexpress various phenotypes of horticultural interest. Through thetransformation of tomato, the expression of genes can be altered toenhance disease resistance, insect resistance, herbicide resistance,stress tolerance, horticultural quality, and other traits.Transformation can also be used to insert DNA sequences which control orhelp control male sterility or fertility restoration. DNA sequencesnative to tomato as well as non-native DNA sequences can be transformedinto tomato and used to alter levels of native or non-native proteins.Various promoters, targeting sequences, enhancing sequences, and otherDNA sequences can be inserted into the genome for the purpose ofaltering the expression of proteins. Reduction of the specific activityof specific genes (also known as gene silencing or gene suppression) isdesirable for several aspects of genetic engineering in plants.

Genome editing is another method recently developed to geneticallyengineer plants. Specific modification of chromosomal loci or targetedmutation can be done through sequence-specific nucleases (SSNs) byintroducing a targeted DNA double strand break in the locus to bealtered. Examples of SSNs that have been applied to plants are: fingernucleases (ZFNs), transcription activator-like effector nucleases(TALENs), engineered homing endonucleases or meganucleases, andclustered regularly interspaced short palindromic repeats(CRISPR)/CRISPR-associated protein 9 (Cas9), see, e.g., Songstad, et.al., Critical Reviews in Plant Sciences, 2017, 36:1, 1-23.
